I'm considering installing a Toto Ultramax to replace an old, water wastingtoilet in an older(1956) home.I've read that these older sewage out pipes require toilets to have greaterdrain-line carry to move the waste sufficiently.In your experience, does the ULtramax work well in older homes/pipes ORwould a toilet with more carry be needed (i'm thinking along the linesof gerber ultraFlush).
